Access:
• Z1: Data of Z1 Measurement
Data Z1 necessary to calculate pen pressure.
When pen detection is enabled (PENDET set to ‘1’ in ADC_TSMR register), Z1 is tied to 0 while there is no detection of
contact on the touchscreen (i.e. when PENS bitfield is cleared in ADC_ISR register).
• Z2: Data of Z2 Measurement
Data Z2 necessary to calculate pen pressure.
When pen detection is enabled (PENDET set to ‘1’ in ADC_TSMR register), Z2 is tied to 0 while there is no detection of
contact on the touchscreen (i.e. when PENS bitfield is cleared in ADC_ISR register).
Note: these two values are unavailable if TSMODE is not set to 2 in ADC_TSMR register.
